The course of true love does not run smooth – as three of the four couples featured on Married At First Sight have learned.

In an absolutely shocking turn of events three of the four of the couples, two of which were seriously loved up, didn’t make it past the five month mark.

The show was set up as an experiment to see if science could find true love for eight unlucky-in-love people and while at first it appeared to have been successful, the last few minutes of the hour and 35 minute show revealed it was not meant to be.

Especially shocking as ALL of them had decided they would give marriage a go.

Sara and Adam, Steve and Lucie, and Clark and Melissa all called it quits, despite two of those three couples showing serious promise.

They ended up struggling a great deal in the five months after their wedding and opted instead to spend time getting to know each other, despite having got a flat together and having bought all manner of furniture.

And Adam and Sara decided to just stay friends too.

Love is dead.

Well not quite, as Adam and Caroline proved a success story, hooray, having had time apart while they looked into moving together, with Adam in Bournemouth and Caroline in London.

They managed to sort that out and just as the programme closed they announced that after 100 days of marriage they had a new arrival – a pet rabbit named Nigel.
